-----------------------------------------
Summary: Cassandra non-seed node doing auto_bootstrap from other DC
Key: CASSANDRA-15681
URL: https://issues.apache.org/jira/browse/CASSANDRA-15681
Project: Cassandra
Issue Type: Bug
Components: Consistency/Bootstrap and Decommission
Reporter: Chris Kistner
I was always under the impression when using "NetworkTopologyStrategy" for a
keyspace that bootstrapping a non-seed node would stream the data from the
local DC.
In my test environment I'm busy adding a third node to dc2, with
auto_bootstrap: true, and it is always streaming its data from dc1 nodes for
some unexplained reason.
The user keyspace (~1GB of sstables for complete data set) has been created
with:
{noformat}replication = {'class': 'NetworkTopologyStrategy', 'dc1': '3', 'dc2':
'3'}{noformat}
Nodetool status is showing:
